Anyone with a mind creative enough to think about space elevators has probably asked themselves the big question. The one that smart people don't bring up because it often degenerates into a conversation that sounds like a rejected Twilight Zone script.
IS THERE LIFE ELSEWHERE IN THE UNIVERSE?
The Cité des Sciences et de l'Industrie and CNES, France's National Centre for Space Studies put together an excellent and fun web collection of videos and texts examining the question.
This post started out to be a humorous one about the but, as often happens, a question posed by one of the presenters stopped me in my tracks. If the building blocks of life on Earth came from space what was the starting point?
I hope the Space Elevator Journal is there to cover it when we find out.
